GM Genuine Parts Remanufactured Windshield Wiper Motors are designed, engineered, and tested to rigorous standards, and are backed by General Motors. Windshield wiper motors are small electric motors that generate enough force to accelerate the wiper blades across the windshield. Remanufacturing windshield wiper motors is an industry standard practice that involves disassembly of existing units, and replacing components that are most prone to wear with new components. Damaged and obsolete parts are replaced, and completed units are tested to ensure they perform to GM specifications. In addition, remanufacturing returns components back into service rather than processing as scrap or simply disposing of them. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).
